Abstract

L'invention concerne une liaison vissée électroconductrice entre deux pièces (10, 12) vissées l'une à l'autre au moyen d'une vis (16) comportant une tête de vis (18) et une tige (22), et d'un écrou (28), la vis (16) s'étendant à travers un perçage (14) présent dans une des pièces (10), le contact électrique entre l'autre pièce (12) et la vis (16) étant réalisé au moyen de dents (27) présentes sur la surface côté pièce de la tête de vis (18) et/ou de l'écrou (28), ou au moyen d'une rondelle de calage disposée entre l'écrou (28) et la pièce extérieure (12), tandis que le contact entre la vis (16) et l'autre pièce (10) est réalisé par des saillies (26) présentes sur la tige (22) de la vis (16), dont le diamètre extérieur est légèrement supérieur au diamètre intérieur du perçage (14), disposées entre le filet extérieur (24) et la tête de vis (18). Les saillies (26) présentent des flancs (42, 44) s'étendant à l'oblique, se rejoignant respectivement à un angle d'environ 60 ° et reliés par des segments en arc de cercle (46, 48).
